2. BACKGROUND

Drug substances are usually administered as part of a formulation in combination with one or more other agents that serve varied and specialized pharmaceutical functions. Dosage forms of various types may be made through selective use of pharmaceutical excipients. As pharmaceutical excipients have various functions and contribute to the pharmaceutical formulations in many different ways, e.g., solubilization, dilution, thickening, stabilization, preservation, coloring, flavoring, etc. The properties that are commonly considered when formulating an active drug substance include bioavailability, ease of manufacture, ease of administration, and stability of the dosage form. Due to the varying properties of the active drug substance to be formulated, dosage forms typically require pharmaceutical excipients that are uniquely tailored to the active drug substance in order to achieve advantageous physical and pharmaceutical properties.

(+)-2-[1-(3-ethoxy-4-methoxy-phenyl)-2-methanesulfonyl-ethyl]-4-acetylaminoisoindoline-1,3-dione (“Compound A”) is a compound with anti-inflammatory activity in clinical development for the treatment of a variety of chronic inflammatory conditions. Pharmacologically, Compound A blocks the degradation of cyclic adenosine monophosphate (cAMP) via inhibition of the phosphodiesterase type IV (PDE4) enzyme, resulting in an increase in cAMP in PDE4-expressing cells including monocytes, T cells, and neutrophils. Enzyme assay data using purified PDE4 enzyme from U937 human monocytic cells indicate that Compound A has a PDE4 IC₅₀ of about 74 nM. Compound A and methods for its synthesis are described, e.g., in U.S. Pat. No. 6,962,940, the disclosure of which is hereby incorporated by reference in its entirety.

Due to its diversified pharmacological properties, Compound A is useful in treating, preventing, and/or managing various diseases or disorders. Thus, a need exists as to dosage forms of Compound A having advantageous physical and pharmaceutical properties.

Without being limited by a particular theory, color change (e.g., fading) is frequently observed in tablet formulations. This phenomenon, known as blooming effect, is caused when lower molecular weight material used in the formulation diffuses to the surface under higher temperature and humidity conditions. For example, excipients such as medium chain triglycerides, which are commonly used as plasticizers in film coatings can migrate or diffuse to the tablet surface causing the color change. However, the phenomenon is not always observed when lower molecular weight materials are used in formulations, i.e., presence of lower molecular weight materials may or may not cause blooming effect. It was discovered that interaction of a particular lower molecular weight material with other ingredients of the formulation, as well as the actual amount of the lower molecular weight material and other ingredients, are critical in assessing whether a particular formulation would exhibit instability in terms of change of color or appearance.

Accordingly, in certain embodiments, the formulations or dosage forms provided herein do not comprise a lower molecular weight excipient that may diffuse to the surface of the composition. In other embodiments, the oral formulations or dosage forms provided herein comprise a lower molecular weight excipient, but at an amount that does not trigger blooming effect. In other embodiments, the oral formulations or dosage forms provided herein comprise a lower molecular weight excipient in the presence of other excipients in a way that blooming effect is not observed in connection with the resulting formulations or dosage forms. Consequently, formulations and dosage forms provided herein exhibit improved stability, particularly in terms of change of color or appearance.

In such an embodiment, the formulations may contain other various excipients such as, but not limited to, coating agents, binders, lubricants, stabilizing agents, plasticizers, adhesives, glidants, and/or diluents.

Pharmaceutical compositions and formulations provided herein can be presented as discrete dosage forms. Although a preferred oral dosage unit form is in the form of a tablet, other forms of dosage forms can also be employed. For example, it is possible to use the core formulation in connection with other forms of dosage forms such as a capsule or a caplet. In some embodiments, the formulation is in the form of a tablet.

In some embodiments, because it is typical to obtain Compound A, or a pharmaceutically acceptable prodrug, salt, solvate, or clathrate thereof, at a purity of less than 100%, the formulations and dosage forms provided herein may be defined as compositions, formulations, or dosage forms that comprise Compound A, or a pharmaceutically acceptable prodrug, salt, solvate, or clathrate thereof, at an amount that provides the potency of a specified amount of 100% pure Compound A.

In certain embodiments, provided herein are anhydrous pharmaceutical compositions and dosage forms including an active ingredient, since water can facilitate the degradation of some compounds. For example, the addition of water (e.g., 5 percent) is widely accepted in the pharmaceutical arts as a means of simulating shelf-life, i.e., long-term storage in order to determine characteristics such as shelf-life or the stability of formulations over time. See, e.g., Jens T. Carstensen, Drug Stability: Principles & Practice, 2d. Ed., Marcel Dekker, NY, N.Y., 1995, pp. 379-80. In effect, water and heat accelerate decomposition. Thus, the effect of water on a formulation can be of great significance since moisture and/or humidity are commonly encountered during manufacture, handling, packaging, storage, shipment, and use of formulations.

An anhydrous pharmaceutical composition should be prepared and stored such that the anhydrous nature is maintained. Accordingly, in some embodiments, anhydrous compositions are packaged using materials known to prevent exposure to water such that they can be included in suitable formulary kits. Examples of suitable packaging include, but are not limited to, hermetically sealed foils, plastic or the like, unit dose containers, blister packs, and strip packs.

In this regard, also provided herein is a method of preparing a solid pharmaceutical formulation including an active ingredient through admixing the active ingredient and an excipient under anhydrous or low moisture/humidity conditions, wherein the ingredients are substantially free of water. The method can further include packaging the anhydrous or non-hygroscopic solid formulation under low moisture conditions. By using such conditions, the risk of contact with water is reduced and the degradation of the active ingredient can be prevented or substantially reduced.

4.1.1. Second Active Agents

In certain embodiments, provided herein are compositions and dosage forms of Compound A, or a pharmaceutically acceptable prodrug, salt, solvate, or clathrate thereof, which may further comprise one or more secondary active ingredients. Certain combinations may work synergistically in the treatment of particular types of diseases or disorders, and conditions and symptoms associated with such diseases or disorders. Compound A, or a pharmaceutically acceptable prodrug, salt, solvate, or clathrate thereof, can also work to alleviate adverse effects associated with certain second active agents, and vice versa.

4.2. Process for Making Dosage Forms

Dosage forms provided herein can be prepared by any of the methods of pharmacy, but all methods include the step of bringing the active ingredient into association with the excipient, which constitutes one or more necessary ingredients. In general, the compositions are prepared by uniformly admixing (e.g., direct blend) the active ingredient with liquid excipients or finely divided solid excipients or both, and then, if necessary, shaping the product into the desired presentation (e.g., compaction such as roller-compaction). If desired, tablets can be coated by standard aqueous or non-aqueous techniques.

A dosage form provided herein can be prepared by compression or molding, optionally with one or more accessory ingredients. Compressed tablets can be prepared by compressing in a suitable machine the active ingredient in a free-flowing form such as powder or granules, optionally mixed with an excipient as above and/or a surface active or dispersing agent. Molded tablets can be made by molding in a suitable machine a mixture of the powdered compound moistened with an inert liquid diluent. Encapsulation of the dosage forms provided herein can be done using capsules of methylcellulose, calcium alginate, or gelatin.

In some embodiments, the active ingredients and excipients are directly blended and loaded into, for example, a capsule, or compressed directly into tablets. A direct-blended dosage form may be more advantageous than a compacted (e.g., roller-compacted) dosage form in certain instances, since direct-blending can reduce or eliminate the harmful health effects that may be caused by airborne particles of ingredients during the manufacture using compaction process.

Direct blend formulations may be advantageous in certain instances because they require only one blending step, that of the active and excipients, before being processed into the final dosage form, e.g., tablet or capsule. This can reduce the production of airborne particle or dust to a minimum, while roller-compaction processes may be prone to produce dust. In roller-compaction process, the compacted material is often milled into smaller particles for further processing. The milling operation can produce significant amounts of airborne particles, since the purpose for this step in manufacturing is to reduce the materials particle size. The milled material is then blended with other ingredients prior to manufacturing the final dosage form.

For certain active ingredients, in particular for a compound with a low solubility, the active ingredient's particle size is reduced to a fine powder in order to help increase the active ingredient's rate of solubilization. The increase in the rate of solubilization is often necessary for the active ingredient to be effectively absorbed in the gastrointestinal tract. However for fine powders to be directly-blended and loaded onto capsules, the excipients should preferably provide certain characteristics which render the ingredients suitable for the direct-blend process. Examples of such characteristics include, but are not limited to, acceptable flow characteristics. In one embodiment, therefore, provided herein is the use of, and compositions comprising, excipients which may provide characteristics, which render the resulting mixture suitable for direct-blend process, e.g., good flow characteristics. In certain embodiments, a dry blend tablet formulation is the preferred way of making the tablets provided herein.

4.2.1. Screening

The process for making the pharmaceutical compositions of the invention preferably includes the screening of the active ingredient and the excipient(s). In one embodiment, the active ingredient is passed through a screen having openings of about 200 microns to about 750 microns. In another embodiment, the active ingredient is passed through a screen with openings of about 200 microns to about 400 microns. In one embodiment, the active ingredient is passed through a screen having openings of about 300 to about 400 microns. Depending on the excipient(s) used, the screen openings vary. For example, disintegrants and binders are passed through openings of about 430 microns to about 750 microns, from about 600 microns to about 720 microns, or about 710 microns. Lubricants are typically passed through smaller openings, e.g., about 150 microns to about 250 microns screen. In one embodiment, the lubricant is passed through a screen opening of about 210 microns.

4.2.2. Pre-Blending

After the ingredients are screened, the excipient and active ingredient are mixed in a diffusion mixer. In one embodiment, the mixing time is from about 1 minute to about 50 minutes, from about 5 minutes to about 45 minutes, from about 10 minutes to about 40 minutes, or from about 10 minutes to about 25 minutes. In another embodiment, the mixing time is about 15 minutes.

When more than one excipient is used, the excipients may be admixed in a tumble blender for about 1 minute to about 20 minutes, or for about 5 minutes to about 10 minutes, prior to mixing with the active ingredient.

4.2.3. Roller Compaction

In one embodiment, the pre-blend may optionally be passed through a roller compactor with a hammer mill attached at the discharge of the compactor.

4.2.4. Final Blend

When a lubricant, e.g., sodium stearyl fumarate and magnesium stearate, is used, the lubricant is mixed with the pre-blend at the end of the process to complete the pharmaceutical composition. This additional mixing is from about 1 minute to about 10 minutes, or from about 3 minutes to about 5 minutes.

4.2.5. Tableting

The formulation mixture can be tableted (e.g., via compaction, compression, or molding) into the desired size and shape tablet using, for example, a tablet press or other conventional tableting equipment and standard techniques.

4.2.6. Encapsulation

The formulation mixture can also be optionally encapsulated into the desired size capsule shell using, for example, a capsule filling machine or a rotary tablet press.

4.3. Kits

Pharmaceutical packs or kits which comprise pharmaceutical compositions or dosage forms provided herein are also provided. An example of a kit comprises notice in the form prescribed by a governmental agency regulating the manufacture, use or sale of pharmaceuticals or biological products, which notice reflects approval by the agency of manufacture, use or sale for human administration.
